Hi all , can anyone tell me where I can purchase and upgrade FD alternator ? Thanks in advance.

Get in contact with IRP here on the forum, they offer a higher Amp alternator upgrade for much less than the link above.

 

I'm not sure if they do it anymore but yes IRP is where mine was done.

Rotary experiment seven can help you out. Shoot him a PM.

Goodfellafd3s can help you out as well but he is away. He may be able to answer questions though.

 

Yes we still offer them. Pm me for details please or contact me at the shop.

 

You can also try Sportuner.com, the owner is a rotorhead.

 

IRP/Sport Tuner alternator is the same. It was a combined effort.

 

Good to know, thanks.

 

You may also be able to find a local alternator shop that can build you a custom one by modifying the internals of the factory unit. That's what I did, I think it was $150.
